Some fun, simple, examples for common scripts and stuff!

[armanbilge]

Here's the one posed by Virtus Lab:

Imagine you have a common business problem to solve. You need to write a program that fetches text from a web service and then creates a file in the local filesystem with content and path based on the downloaded information.

Scala Toolkit is getting a bunch of tutorials / examples, we can cheat by copying those and then slapping on a parTraverse 😝

• Add tutorials about MUnit in the Scala Toolkit scalacenter/docs.scala-lang#8

“Hands On Scala” (Haoyi's book) is a good source to raid for ideas on this, IMO

[TonioGela]

Is this gist of mine a good idea?

I felt the urge of being able to do

$ echo -e "foo\nbar" | mkString --prefix '{' --suffix '}' --delimiter "~"
{foo~bar}

with huge files, so I leveraged fs2 and ScalaNative to overkill the task 😇

had a quick go at the virtuslab example for the fun of it:

Thanks @Koroeskohr! I'll create an examples folder and add it.

I have some troubles running it though, I'm getting this 👇 running it with "3.2.2". Is it just me? 🤔

I'll create an examples folder and add it.

Alternatively, let's consider setting up a website with mdoc-checked examples. It will be easier to browse maybe? Edit: and also enables us to add exposition.

Yep, I was just thinking that having a site might be ideal

[Koroeskohr]

@TonioGela i copied the virtuslab one-for-one that doesn't work either, I can polish it so that it's runnable, probably better

[Koroeskohr]

@TonioGela updated it

[TonioGela]

Thanks @Koroeskohr, I'll add it to the site once published :)

@TonioGela continueing here about the Pokemon example:

Well, how about a stuffed example that:

accepts from command line a pokemon kind
writes a csv with all results (restricted to a few properties)

Will it be too long? OFC I don't know if that search-ish API exists
[EDIT] there's https://pokeapi.co/docs/v2#types :D

I think this is good! I should probably have it's separate page because it'll be a "big" example, but honestly it showcases some cool stuff.
